Image Log Interpretation

Image log interpretation is the subject of a short course taught at AAPG’s Summer Education Conference in Fort Worth. The course, which will be held on June 18 & 19, will show the range of interpretations possible with image log data sets. This range includes geological analyses such as depositional bedform analysis, diagenetic alterations to the rock, sedimentological sequences, quantifying thin-bedded reservoirs, structural analysis of folded and faulted structures, and the analysis of fractures and fracture sets. The instructor, Dr. Laird Thompson, is currently a professor at Utah State University and has publications on Borehole Image Logs, Fracturing Modeling, and numerous in-house reports on specific wells, fields, and training manuals for borehole imaging and fractured reservoirs.

By the end of the course, participants will be able to:

  • Know the different image logging tools and which ones to use in different hole conditions and for solving different problems.
  • Know how to QC an image log to be sure the data are reliable. Know how the image is created and understand its’ strengths and limitations.
  • Know how to work with at least two different image log interpretation software systems and how to evaluate the most appropriate software for different interpretation needs.
  • Know how to identify artifacts on image log data and distinguish them from the geological information in the image log.
  • Know how to work with depositional bed forms and sequences for doing a sedimentological analysis.
  • Know how to recognize faults and fractures on image logs and how to gather these data for use in 3D fracture modeling.
  • Know how to recognize drilling induced fractures vs. natural fractures in the rocks.
  • Know how to recognize and use geomechanical features for wellbore stability and mud weight predictions.
  • Know how to extrapolate structural information away from the wellbore to predict near-by drilling opportunities.

The course, which is a part of the Summer Education Conference, will be beneficial for geoscientists and petrophysicists who use image log interpretations in their reservoir interpretations and are looking to expand their knowledge of the application of image log data sets to solve a variety of industry problems.
